无法控制黄瓜的并行执行

Question

我无法控制来自 dataproviderthreadcount 的进程。例如，如果我们有 4 个场景并且我运行我的脚本，它会并行执行所有 4 个场景。我在 pom 中为 maven-surfire 提供的 dataproviderthreadcount 值并不重要。

下面是截图。

import io.cucumber.testng.CucumberOptions;
import org.testng.annotations.DataProvider;


@CucumberOptions(
        plugin = {
                "pretty",
                "json:target/reports/json/result.json",

功能 1：

Feature: test 1

  Scenario: 01
    Given Print "01"

  Scenario: 02
    Given Print "02"

  Scenario: 03

  Scenario: 04
    Given Print "04"

如果有人知道如何控制线程数而不是让 Testng 决定，请告诉我。

Answer 1

TestNG 本身没有问题。

您在 pom 文件中设置的 dataproviderthreadcount 属性仅在您通过 mvn clean test 进行测试时才适用和相关。

如果您尝试从 IDE（IntelliJ 或 Eclipse）中运行此测试 class 它不会生效。

这是我创建的测试 class，由数据提供者提供支持（为了简单起见，我特意将黄瓜排除在方程式之外）

import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class AppTest {

  @Test(dataProvider = "dp")
  public void shouldAnswerWithTrue(int i) {
    System.err.println("Running on [" + Thread.currentThread().getId() + "]");

  }

  @DataProvider(name = "dp", parallel = true)
  public Object[][] testData() {
    return new Object[][]{
        {1},
        {2},
        {3},
        {4},
        {5},
        {6}
    };
  }
}

这是我运行 mvn clean test

时的命令行输出

Answer 2

我遇到的一模一样。正如 Krishnan 提到的，pom.xml 中的 dataproviderthreadcount 仅在您运行 mvn test 但没有任何参数时有效。如果要指定 xml 到运行的套件，您还需要在命令行中添加 -Ddataproviderthreadcount=2。例如，“mvn -Dsurefire.suiteXmlFiles=suite.xml -Ddataproviderthreadcount=2 test”
